Pleased to see that there is a bat using our bat box again.
A couple of years ago I noticed that bats were hanging onto the back of the two old pictures we have hanging in the summer house. As many as three on one picture, so I found a plan for a basic bat box, made it and found it worked and the bats used it.
We haven't had one in it for a while. I checked it about ten days ago and it was empty, so it was great to see one in it today. We see lots of bats flying around as dusk falls.
